Disney released a behind-the-scenes video with Imagineers detailing upgrades to Big Thunder Mountain Railroad at Magic Kingdom ahead of its May 3 reopening, including a smoother new track, updated vehicles, control system, and shimmering Rainbow Caverns.
Following yesterday's announcement of the ride's May 3, 2026, reopening after over a year's refurbishment, Disney shared exclusive footage of the Imagineers involved. They showcased the all-new track, replacing the previous rickety version for a smoother yet thrilling experience. New ride vehicles and an upgraded control system enhance guest comfort while preserving the Wildest Ride in the Wilderness. The attraction now features a vibrant Rainbow Caverns scene with iridescent, illuminating effects. The exterior has been refreshed to better integrate with the upcoming Piston Peak expansion in Frontierland. Imagineers teased additional unspecified magic for riders. The height requirement drop to 38 inches (from 40) opens the ride to more young guests.
